Be it known ,that I, SAMUEL L.4 Tiin'rionn, a 4citizen of lthe United States, residing vat Boligee, in' the countyfof Greene and State of Alabama, have invented certain/new and useful Improvementsl in Harvesters, of which the following is a specification.4

This invention relates r,to agricultural implements, and more Vparticularly ,tol supporting devices for agricultural tools.

An object of the invention is the provision of an agriculturall implement comprising awheeled frame `and an auxiliary frame pivotally connected 4to the wheeled frame to permit adjustmentthereof.

A. further object is the provision of an adjustable auxiliary frame having a transversemember adapted to form a guide or' support for the agricultural tools.

Other objects and advantages of the vinvention will be apparent during the course of the following description.

In `the accompanying drawings forming a part of this specification, and in which like numeralsare employed to designate like parts throughout the same:

Figure 1 is a plan view of a machine embodying my invention;

Figure 2 `is a side elevation of the same, parts being shown in section; and

Figure 3 is a front end elevation of the machine.

The machine comprises a rectangular frame 5, including longitudinal beams 6, connected near their forward ends by transverse beams 7 The rear ends of the beams 6 are connected by a rock shaft 8, pivoted thereto, as shown at 9. This rock shaft has end elevating cranks 10, arranged upon and adapted to engage supports 11 secured to the rear ends of the beams 6, and preferably formed by twisting the ends. The rock shaft 8 is provided centrally thereof with a crank 12, to be operated by means to be 'designates an inner frame, embodying longitudinal beams 17, having their rear ends pivotally receiving the shaft 13, any suit,- able means being employed to prevent thesev beams moving longitudinally of the shaft.

At their forward ends, the beams 17 conrale. serial Ngfsoaze. f

The xnumeral 43 designates a 'vertically' adjustable "supplemental frame,"y comprising approximately Vsh'ap'ed 7membeifs` 44, ythe' forward ends ,of which are p ivted u'penv the ale 13. These V-,shap'e'd members are" coni Iiect'edl at their tops by a transverse st'r'p45,

secured'to'the inner beam 7, as

while their lower ends are connected by` a crank shaft 46. The horizontal or lower arms 47 of the supplemental frameengage and are supported by elevating cranks 10,

' having extensions 48, whichv prevent lateral displacement thereof. The rock shaft 8 is turned by means of the link 49 pivoted to the crank 12, and this link is pivotally conneeted with a lever 50, which is pivoted to a quadrant` 51, carried by a stationary plate 52, in turn secured to the longitudinal beam 17. The lever may be equipped with theusual latch mechanism to lock it againstk It is thus seen that 3 by'moving the lever forwardlyl the cranksv improper movement.

The means to agitate the dug plants or vines to free the fruit from the earth em-` body a plurality of forks. 59, which' are preferably longitudinally curved and faced rearwardly` lmingthe top of the soil and picking up the vines, agitating the same and freeing th fruit from the dirt.

The operation of the machine is as fol-` lows:

is drawn or propelled for- The auxiliary frame lmay be supported on the main f frame at any desired adjustment and the tools k59 are rotated about a vertical axis, by the crank shaft 46. In the present illustration, I have shown rakes adapted to lift dug plants and fruit to completely free the plants and fruit from the soil. It will be These forks are carried by` upstanding handles 60, to the upper end of l Secured apparent that any other type of tool may be employed in place of the rakes.

It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted to Without departing from the spirit of the invention or the scope of the subjoined claim. c

vHaving thus described my invention, I Aclaim- An agricultural implement comprising a Wheel frame, an auxiliary frame pivotally connected with the Wheel frame to be swung in a vertical plane, said auxiliary frame comprising a pair of substantialy V-sha ed side bars, said side bars being connecte to the Wheel frame at the point of intersection of the tvvo arms, cranks connecting the free.

ends of one of the arms of each of said side bars to the Wheel frame, a crank shaft on which said cranks are arranged, an operating lever mounted on the Wheel frame, connections betweensaid lever and said crank shaft, a transverse member connecting the free ends of the other arms of the V-shaped side bars, and agricultural tools passing through said transverse member.

In testimony whereof I afix my signature 30 in presence of two Witnesses.

SAMUEL LEV/'IS THETFORD.
